Type material.

Syntype NHMUK 1954.6.2.1542-1544 (3 shells; Fig. 3G, H).

Remarks.

The original description did not include an illustration or state the number of specimens examined and there is no information concerning the operculum, however one set of shell measurements were given. Later, Pfeiffer (1860b) and Reeve (1861) re-published the description and figured the species from specimens in the Benson collection. There is a type lot in the NHM ex. Hawkins collection containing three shells (1 with and 2 without periostracum). The specimen without periostracum that most closely matches with the measurements given in the original description and the illustrations in Pfeiffer (1860b: pl. 37, figs 25-27) and Reeve (1861: pl. 20, species 104) is figured herein (Fig. 3G).
